Which of the following describes a contract that has no legal force?

A contract that has no legal force is classified as "void and unenforceable." This designation indicates that such a contract is treated as if it never existed in the eyes of the law, meaning that it cannot be upheld in a court of law. Examples of void contracts include those that involve illegal activities or contracts made by individuals who lack the capacity to enter into a contract, such as minors or mentally incapacitated persons.

In contrast, a valid but unenforceable contract may have legitimate elements and could be legally binding, yet it cannot be enforced due to certain legal defenses or restrictions. Implicit contracts are typically formed through actions rather than written or spoken words, and express contracts are explicitly stated in writing or verbally. These types of contracts may hold legal weight but are distinct from the concept of being void in legal terms.
